摘　　要：针对低温低浊水出水浊度不达标的问题进行了絮凝试验研究。结果表明,投加混凝剂聚合氯化铝(PAC)或聚合氯化铝铁(PAFC),剩余浊度、剩余CODMn均有所降低,继续加大投药量,浊度反而升高。进一步试验表明:在PAFC用量为12 mg/L,改性活化硅酸用量为0.12 mg/L条件下,剩余浊度、剩余CODMn分别达到0.21 mg/L和0.64 mg/L。改性活化硅酸的投加时间对混凝效果有一定的影响,混凝开始后330s投加改性活化硅酸可以提高混凝效果。Because low turbidity and low temperature water cannot come up to the water quality standard, a series of tests were conducted to solve this problem. The results show that dosing coagulant PAC or PAFC, residual turbidity and residual CODM~ were decreased. When continue to increase the dosage, the turbidity increased. Further tests showed that in the amount of PAFC 12 mg/L, the amount of activated modified silicic acid 0.12 mg/L condition, residual turbidity and residual CODMB respectively 0.21 mg/L and 0.64 mg/L. Activated modified silicic acid dosing time on the coagulation effect to a certain extent, 330s after the start of coagulation dosing activated modified silicic acid can improve the coagulation effect.
